I have had delivery of an ex-demonstrator GS3 this week - love the coffe it makes, but how do you turn it OFF!?!? I have followed the user guide - press and hold button number 5 and then press the tea button (no.6) - all that happens is that hot water pours out of the hot water spout? It's not shutting down like it should. Is it OK to simply flip the main on/off power switch on the back? I'm worried about causing damage. Any tips gratefully received.

Fred, Please do not circuit breaker ON/OFF your precious GS3, as this can surge the CPU. Is it possible you've accidentally entered programming mode and reassigned buttons. There are a few other issues it could be. How many seconds does the hot water flow?Usually holding down a LM button enters programming mode. It is easy to cure with - www.chriscoffee.com/products/home/espresso/lamarzoccogs3Julian

Hi Julian -thanks for the reply - the hot water flows until you manually stop it. The software version is 1.05 and the user guide I have downloaded from Chris Coffee is 1.09, so not sure if it is all relavent. I can get it to automatically power on and off using the timer, which is the only way I can figure out how to shut it down at night! I'm a home user, and need some flexibility to turn the machine off and on depending if I'm around or not.

Fred,It is OK to turn on and off the machine with the switch in the back. There is no power surge to the CPU by doing so. Turning off the machine with the keypad only changes the program the CPU is running and does not heat the boilers or monitor the sensors. The CPU is running in the same condition in the ON and OFF mode (at the keypad). Turning off the machine while the machine is ON or OFF (at the keypad) makes no difference to the CPU.The buttons cannot be reassigned in the software so either the button is not being activated while you are holding it down or you may not be pressing it correctly. When you press the button listen closely for a clicking sound, indicating that the switch is activated. There are 2 switched behind the buttons located on the top and bottom of the button. If you cannot hear the clicking sound press closer to the top or bottom of the button.

Thanks Bill - very reassuring. I actually managed to figure it out..... the instructions say press and hold down the 5th key and then the power/tea button - I translated this as meaning hold it down for several seconds but hat only got me into programming mode, but it only needs a second and keep holding it down and press the power button. Works fine now. It was extremely nice to set the timer and come down to a properly warmed up machine ready to go this morning. Now I have figured it out, I'll have to pass on clear instructions to the family!

The GS/3 has a pretty vague manual. All of the drawings and crude pictures of the gauges are actually showing you the Factory Pre-Sets for the PID in whatever part of programming you are in, whether it is "Machine Off" programming or "Machine On" programming. Machine On programming is the one designed for the homeowner; be careful you understand what you are doing in the "Machine Off" programming.
